Step 2Prep the Solar Cell and other stuff
I check the cell (in the sun light) for polarity that means which contact is + and - (if you don't know how to use a voltage meter search the ALL KNOWING INTER-WEB)
I also checked the polarity of the plugged in charger I marked the + wire with tape. Then I cut the wire in half. We only want the side that goes in the cell phone.
